 Okay, did you key and if we present this week's Ion MPI is from T.E. Lady Eda. T.E. is back. They've been on Ion MPI a couple of times, but they keep coming up with interesting new products. And so they get the MPI prize. They keep making new products. We'll keep making MPI. That's right. That's cool. Okay. So this week, I've actually noticed a bunch of companies that do sensors are also releasing sensor revisions around now. Don't know why, maybe just at the end of the year, they want to get those versions out. But this week's new product is the HTU 31D and 31V. These are temperature and humidity sensors from T.E. They've got excellent temperature humidity sensors. In fact, you might be thinking, don't you already have a breakout for that HTU 31? No. You're thinking of the HTU 21, which is still one of my favorite temperature and humidity sensors. Really easy to use, very reliable. I've got that great I2C interface that's very simple, but complete. And it's a couple of years old now. It's a couple of years old. And I think they want to revise it, update it, make it a little bit better. The HTU 21, I think, had maybe half a degree of accuracy and 3% or 4% percent humidity accuracy. And the HTU 31 improves that. It's got 0.2 degrees centigrade Celsius accuracy for temperature and for humidity, it's about 2%. So a nice big improvement there. The pinout is not the same. The package is the same, but the pinouts a little bit different. As you can see here, it still has I2C, as you would expect. But it also adds a reset pin, and you also get an I2C address selection pin. That's good. You can alternate between, I think, 41 and 42 or the two I2C addresses. And there's a hard reset, which I always like to have. It's nice to be able to hard reset a sensor along with a microcontroller in case it gets into an unusual state. There's also a software reset. Speaking of what I really like about these sensors is how they can do pretty much everything you want in a temperature and humidity sensor. And they don't have a ton of extra stuff to confuse you. It's pretty straightforward. They have software reset. You can turn the heater on, turn the heater off. Which is great for reducing power, but also to get any moisture off of the sensor. To reading the actual air or humidity, not like the humidity on the sensor. There's a bit of water on there. You can read the relative humidity as well as the temperature and humidity. There's a diagnostic result that gives you about a couple bits of information about how the device is doing. And there's a unique, I think it's 32-bit or 24-bit serial number. So you have all the nice things that you want. And there's also a CRC capability. So when you send and receive commands, there will be a cyclic redundancy check to make sure that the data isn't being corrupted. You're getting valid temperature and humidity data. I think that's important, especially for people who want to use this for medical uses or they want to control home automation or environmental stuff. You don't want to like actually turn on the sprinkler. It turns out that there was like a, you know, a bit flipped or a loose wire that made you think that it was very dry, but actually wasn't. So a nice compact, but efficient and complete command set. We were able to get it up and running in Arduino. We wrote a library a couple weeks ago and it was up and running in like an hour or two. It was very easy to implement in Arduino and you can definitely port it to your favorite microtroller quite easily as well. So check out our library if you want some Arduino code to try with this sensor. There's also another version. I do like the HTU 31D that's for digital iSquared C interface, but they also have a V version for voltage. And I thought that was just kind of interesting because it's not that common that you see sensors these days with raciometric analog voltage output. I mean, it's really cool and I remember, you know, the first accelerometers like the ADXL 335 that came with raciometric output a long time ago and then everyone sort of went over to SPI or iSquared C. So I really like that TE is bringing back the raciometric analog voltage outputs. You know, basically you can power it with three to five volts and then whatever that power voltage is, that's the high end of the analog voltage output. So as long as your analog reference is tied to the same power pin, you'll always get the accuracy and precision that your microtroller analog digital input will provide. Why is this handy? Well, first off, maybe you really want a lot of these and you don't want them to share on iSquared C. Maybe you don't want the iSquared C traffic. Maybe you want to have this in a circuit that doesn't have a microtroller as the feedback loop. You want to have a more, like a faster, more reliable, less like complicated loop and you just want that analog voltage with, you know, a potentiometer to set the trigger point, maybe some hysteresis with the Schmidt trigger and then, you know, you could you could use the analog output in your circuit or feedback loop. What is it really good for? I don't know exactly, but I think it's pretty cool that they have a version with analog voltage out. So I'm going to check that out. Here's what it looks like. They give you a little graph showing it. It's pretty linear, you know, at the very beginning at the very end, it gets a little bit. I'm linear, so you might do a little bit of math, but for the most part, you know, voltage input, temperature output. Okay, so you can get these, they come in a couple different packages. There's a wheel of 150 and it says like 150 in the part number. And then there's a wheel of 400. So you're wondering what's the difference between the 150 and 400. It's just how many are in a wheel. The component is the exact same. You can pick it up from Digikey. You can search for h231d or it's got this longer part number. 2 2 3 1 0 1 4 2 0 4 8 0 and D or the short URL digikey.com for a short URL z1hjhj. Which is pretty easy to remember. They don't yet have a version with the Teflon covering on it, which they did for the h221d. I'm hoping that comes out soon. It was really one of my favorite things about the h221d. So, but so far I'm really liking it. It's extremely fast and it's very stable. So I think they did a good job kind of leapfrogging. You know, they've updated the sensor in a bit, but when they did, they did an excellent job. So you want to go to the overhead and I'll show the demo. I've got the sensor here. I've got it hooked up to my feather and I've got an OLED just showing the temperature and humidity. It's not very humid here to be honest. Temperature is nice and comfy though, nice room temperature. And then if I breathe on the sensor, which is right here, you'll see how fast and responsive it is. It's already, you know, goes up to 60 and then quickly drops down. So I definitely like how responsive the humidity sensor is. It's very quick and it's very stable. You know, once it settles, you know, within 1% you're going to keep that precision. The accuracy is, you know, 2% plus or minus, but the precision is nice and stable, which I really like. All right. And they have a one minute video and we're going to play it. It's actually pretty chill. It's just like usable. It's super chill. Yeah, so enjoy.
